Copied from where to where?  At what time, at "make check" time?
Please note that "distribution" is what happens at "make dist" time,
not at build ("make all") or check time.

When you say "I am building in a separate directory", do you mean you do
a VPATH build like this:
  mkdir ../build
  cd ../build
  ../project/configure [OPTIONS]

and then from within the directory build/src, the files under
project/src/ are not visible or copied?  Then you should refer to them
using $(srcdir) or so.

Please note that, whether you name any directory in your project src or
not, does not matter.  The "source tree" is the tree where your project
files live.  In the toplevel of the source tree should be the file.  The "build tree" is rooted at the directory in which
you are when you invoke "configure".  The install tree is what only
exists after you type "make install" (roughly).

Back to your issue.  For example, a typical way to set up a testsuite
using shell commands is to create a file in the source tree

add the line

to, and then using this in test scripts:
  . relative/path/to/defs
  # ...
  access test input files like: $srcdir/sample.xml

I hope this helps somewhat, as I've had to guess a bit what you need.
If it doesn't, then maybe it helps if you show what you have and what
commands go wrong (cut and paste them).
